To all whom it may concern:

Be it known that 1, CHARLES BERNARD lVHITE, a subject of the King ofGreat Britain and Ireland, and a resident of Manchester,

in the county of Lancaster, England, have invented new and usefullmprovements in and Relating to Looms for Weaving Pile Fabrics, of whichthe following is a specification.

These improvements relate to looms and to appliances employed thereinfor the production of a warp pile or like pattern in a fabric eitheralone or in combination with a "figured. or other pattern. Suchappliances may be applied to broader looms for the production of anysuitable fabric, but they are particularly applicable to smallware loomsandto the manufacture of coach lace, trimmings edgings, ribbons, or thelike narrow fabric, for the production of patterns which, hitherto, ithas only been possible to produce by hand.

The warp pile loops are formed by means of a wire or by wires which areso disposed and arranged that they may be moved by the jacquardmechanism as desired and according to the pattern required both in adirection along the warp threads and in a direction about transversethereto, so that such wire or wires can be inserted into the shed and bewithdrawn as required.

It will be preferred to employ two sets of wires and their operatingdevices, one along eachside or edge of the warp threads, but

' for the present it will be more convenient to describe theconstruction and operation of one such wire only and its conjoinedparts, although in Figures 1 and 2 of the drawings two sets of devicesare illustrated.

It is in connection with a smallware loom that I will now describe myimproved devices and their operation.

Fig.1 shows in front elevation part of a loom provided with my improveddevices for forming the warp loops. Fig. 2 shows similar parts in plan.Fig. 3 represents a jacquard device for operating the heddles of theloomand also for effecting the operations of the pile loop formingdevice. Fig. 4 shows part of such a device in front elevation. Fig. 5illustrates in side elevation mechanism by which the movement of thepile forming wire may be effected in a direction parallel to the warps.Fig. 6 is a front elevationof such a wire and the parts to Which it isattached. Fig. 7 is a plan of such a wire and its directly operatingparts and shows how the wire may be moved both along the warps andacross them. Fig. 8 is a sectional view illustrating the connectionsbetween the jacquard mechanism and the loom, as well as the properaccessories for working the cross slides.

Upon the breast bar a or other convenient part of the loom frame ismounted a slide 1) which is in guides or on rollers and is capable ofbeing moved in a to and fro longitudinal direction across the loom.Secured to the slide is a frame 0 provided with rods or equivalents uponwhich is mounted a sliding carriage d capable of being moved by itselfin a direction about parallel to the uarps, and also capable ofpartaking in the movement of the slide to which it is attached in adirection across the loom. this sliding carriage or to an extensiontherefrom is a suitably shaped wire e, which, following the movements ofthe slide 1) and the sliding carriage d may be moved both along andacross the warps or in either direction separately so as to form thewarp piles by being inserted in the shed as wires are at presentinserted by hand.

Below the breast beam is pivoted a rocking shaftfwhich has angularmotion imparted to it through an arm 9 which is connected by a cord,chain, or the like to supplemental hooks and grid bars or similar partwhich is brought into action by the jacquard or like mechanism and'isindicated by 71 in Figs. 3 and 4 and is vertically reciprocated bya cordattached to a lever j operated from the crank or tappet shaft and by aspring or weight. As indicated, the hook it, adapted to operate throughsuitable cords the rocking shaft. f, may be brou ht into or placed outof engagement with the grifl' bar through jacquard mechanism 1 of thewell known construction. Also secured to the rocking shaft is an arm orthe upper end. of which is provided with a long pin 1 which engagesbehind the rear face of the sliding carriage d so that when the rockingshaft is actuated from the supplemental hooks and griff bars the armmoves and places the sliding carria e and its accessories in theposition indicatec by the dotted lines in Fig. 5 and as indicated by 2in Fi 7.

The slide b may be moved in one direction across the loom by means of acord n passing over suitable pulleys and attaching it to a suitablejacquard book as at 0 in Fi 3, and its return may be effected by adupl'cate or Attached to similar cord attached to another jacquardlifting hook. This movement of the slide across the loom puts the wire 6in either of the two positions shown in 2 and 3 in Fig. 7. The warpthreads in which the pile pattern is to be formed according to thisinvention are represented by p and they may comprise all the warps in afabric or may be edged by other warps which are woven in the usualmanner or to any desired figured or other pattern. It is the harnessthrough the mail of which the warp threads p pass, the difierent threadsbeing raised or lowered by the jacquard hooks according to the holes inthe pattern card in the usual manner. As shown in this figure a cord nis attached to the left han'dfend of the cross slide 1) and a cord n tothe right hand end. These cords pass over pulleys Q) and 12 attached tothe breast beam downwards to one side of double armed levers u and u theother side of which is joined by a chain or the like which is slack at sto the jacquard hooks 0 for working the cross slide. As shown in thedrawing the slide 1) is in its extreme left hand position. If nowthe'hook 0 is raised, the slide bis moved towards the right'and the pilewire 6 is put across the warp 1). If it is demoved from the right to theleft.

sired to withdraw the wire a from the fabric the hook 0 is raised andthe slide is thereby The for ward motion of the wire in order to bringit in position opposite the shed is effected by means of the mouse traph to the hook of which the cord to is attached which is connected to thelever g on the rocking shaft f carrying the propeller arm m for the wirecarriage.

I When it is desired to form a loop or loops in the fabric the slidingcarriage d which has been normally standing in the position shown by thefull lines in Figs. 5 and 7 is moved along in the direction of thelength of the warps until it occupies the position shown by the dottedlines in those figures and so that the wire a, which is suitablyproportioned and shaped for forming a warp loop, is opposite to the shedin the position shown by 2 in Fig.

7. The cross slide 1) is then moved in a directionacross the fabric andthe frame and sliding carriage attached to it are moved with it so thatthe wire enters the shed and occupies the position inside the shedformed in the warp threads as indicated by the numeral 3 in Fig. 7. Theradial arm m owing to its only making contact by the pin rbehind therear face of the sliding carriage, has now, owing to its release fromthe supplemental hooks and riif bars been withdrawn entirely from thesli ing carriage, and the wire and the sliding carriage d to which it isattached are free to be moved by the reed into the fell of the cloth onthe next beat of the lathe, and as the shed is closed the loop or loopsis or are formed around the wire. As further picks are made the wire andthe sliding carriage move with taken place or when the wire is againrequired it is withdrawn from the loop or loops by a reverse movement ofthe cross slide. The wire is then inposition for a repetition of themovements already described.

It is highly important that the movement of the slide 12 and the slidingcarriage inwards or transversely to bring the Wire e to the positionindicated by the numeral 3 in Fig. 7 should notbe effected until theshed is fully open and when the slide 5 is operated from or by the samejacquard mechanism as the heddles, this may be accomplished by formingthe cord n by which the slide 1) is operated with a certain amount ofsurplus length as indicated at s in Fig. 3, so that the slide is notmoved until a certain lift of the different hooks has taken place. Thetravel of the slide is of course thus of less length The relative thanthe stroke of the hooks. movements of the sliding carriage and theslide'should be, that the sliding carriage is first moved to its outerposition as shown by the dotted lines in Figs. 5 and 7 and then theslide should be moved to insert the wire in the shed as indicated at 3in Fig. 7.

Although I have described my improvements as relating only to one Wireand its sliding carriage and slide arranged in connection with one edgeof a fabric and although one such wire only may be used if desired, twoare preferred to be used one on each edge of the fabric and eachprovided with its cross slide and sliding carriage, the

necessary operating and other parts being duplicated Where necessary oras required. With two such wires any one Wire may be left longer in theshed before it is removed to.

the same letter of reference with the addition of a numeral 1'; thus thesecond slide is indicated at b and so on. Similarly three or more wiresmay be employed, arranged two or more on each or either side of thefabric and preferably arranged above and below the cloth on any oneedge, the wires being suitably cranked, bent or shaped .to enter theshed.

The supplemental hooks and grifi bars, and jacquard mechanism generallyis of the usual construction and is well known. It will be well known toany one skilled in the, art to so form the cards as to bring the Wiresinto operation as desired to form any desired pattern. The shedding iseffected in the usual manner. a

As is usual and well known with wires which have hitherto been used forforming warp piles, the ends of the wires may be formed as knives orwith cutting edges, so that as a wire is Withdrawn the loops which havebeen formed round it are cut. The loops may be left as loops in thepattern or they may be cut in the ordinary manner.

Having now described my invention what i claim and desire to secure byLetters Patent 1s:

1. In a loom for weaving pile or loop designs, a loop forming wiremovable laterally to and also parallel to the warps, jacquard mechanismfor operating and controlling the movement of such loop forming wire,means,

connecting said jacquard mechanism and the wire by which said wire ismoved directly transversely to the warps, supplemental hooks and griffbars for operating the wire parallel to the warps, a cam forreciprocating such supplemental hooks and griff bars, and a connection.between the supplemental hooks and riff bars and the jacquard mechanismfor t rowing said supplemental hooks and grifi bars in and out ofaction, substantially as described.

2. In a loom for weaving pile or loop designs, a loop forming wiremovable both laterally to and parallel to the warps, jacquard mechanismfor operating and controllin the movement of such loop forming wire, a texible connection between said jacquard mechanism and the wire adaptedto move such wire transversely of the warps, a slack length in saidflexible connection, supplemental hooks and griff bars for operating thewire parallel to the warps, a cam for reciprocating said supplementalhooks and grifl bars, and a connection between the supplemental hooksand gri'ff bars and the jacquard mechanism arranged to throw saidsupplemental hooks and grifl' bars into and out of action, substantiallyas described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

CHARLES BERNARD WHITE.
